maybe I misunderstood this item. Tyson was not a multi-round fighter, although he had no problems with it in his first career, but he was never a fighter who got better the longer the fight went on. I meant his cardio. That the pace of the fight slowed down the longer it went on. He wasn't as durable as Frazier, he didn't distribute his strength like Ali but maybe, as I mentioned, I'm taking it wrong
